Probably Spider Man. I mean, PS4 already has God of War, and even for those that didn't re-buy GOW3 if they enjoyed the GOW games on PS3 you'd assume many of them would have upgraded to a PS4 already by now. While there isn't really any Spider Man on PS4 yet, and is also part of a huge franchise as well.

So far the bestselling Spider-Man game sold 4.5m on PS2 and God of War III sold around 6.5m on PS3 (still under-tracked gave up that fight years ago). I think both upcoming games will sell better than those did and the gap will be closer.
